McGee, the first of several women to claim an affair with Jesse James, lodged her second attack on Handler via Facebook on Friday.

"Dear Chelsea, glad to see my grandma's old clothes put to good use in your wardrobe. Her mu-mu's look AMAZING on you," McGee wrote Friday after Handler called her a "dumb bitch" on a recent episode of Chelsea Lately.

"P.S.," McGee, 32, sniped, "You need to hire another midget to hold up those saggy boobies of yours...all that breast feeding from Chuy has really taken its toll" (Chuy Bravo is Handler's personal assistant who appears on her E! show.)

To be fair, comedienne Handler, 35, started the fight when she wrote on her E! blog, "Michelle really believed that Sandra [Bullock] and Jesse were separated and was 'shocked' to see them together at the Oscars. I guess she doesn't read magazines, which makes sense since she basically has one on her face."

Offended by the tattoo jibe, McGee first retorted on Facebook that Handler should "use some of that botox from your forehead and put it in your flabby underarm skin..I've seen better wings in a bucket of KFC chicken."
